Analyze routing basics and static routes
What is routing:
The so-called ""routing"" refers to the behavior and actions of transferring data from one place to another, and the router is the machine that performs this kind of behavior. It is a network device that connects multiple networks or network segments. Data information between different networks or network segments is ""translated"" so that they can ""read"" each other's data to form a larger network.
The router has the following main functions:
First, the network interconnection, the router supports a variety of local area network and wide area network interfaces, mainly used to interconnect the local area network and the wide area network, to achieve different networks to communicate with each other.
Second, data processing, providing functions including packet filtering, packet forwarding, priority, multiplexing, encryption, compression, and firewall.
Third, network management, routers provide configuration management, performance management, fault tolerance management and flow control.
In order to complete the work of ""routing"", the routing data table of various transmission paths is stored in the router for routing. The routing table stores the information of the subnet, the number of online routers, and The name of the next router, etc. The routing table can be fixed by the system administrator or dynamically modified by the system. It can be automatically adjusted by the router or controlled by the host. Two addresses are involved in the router. Name concept, that is: static road table and dynamic routing table. The fixed routing table set by the system administrator in advance is called static routing table. Generally, it is preset according to the network configuration when the system is installed. It does not change with the change of the future network structure. The dynamic routing table is a routing table that the router automatically adjusts according to the operation of the network system. The router automatically learns and memorizes the network operation according to the functions provided by the routing protocol, and automatically needs when needed. Calculate the best path for data transmission.
Static routing protocol:
Referring to the hierarchical protocol, when a well-packaged packet arrives at the router, because the router is a Layer 3 device, the packet is stripped from the frame and passed to the network layer. If the packet meets the routable condition, the router looks up its own routing table. Find the corresponding routing entry and forward the packet.
